Abstract

The treatment of a segregated textile wastewater containing reactive dyes was investigated in two continuous‐flow process trains using ozonation and biological processes. The degree of decolorization and dissolved organic carbon (DOC) removal achieved by ozonation followed by aerobic treatment (two‐stage) was compared with that found when an anaerobic and aerobic pretreatment was added (four‐stage). Although the biological pretreatment reduced color by ∼70%, similar amounts of ozone were required in both trains to achieve high degrees of overall removal of color and DOC. In both trains, ozonation increased biodegradability in the following aerobic reactor, however, in order to reach ∼80% overall DOC removal, a specific ozone absorption (A*) of ∼6 gO 3 gDOC o−1 was required and >50% of the DOC was mineralized in the ozone reactor. A comparison of cost estimates based on investment and operating costs for the process alternatives showed that a four‐stage train would reduce costs only if it enabled a decrease in A* to less than 2 gO 3 gDOC o−1. Difficulties in comparing treatment processes for segregated vs full‐stream wastewaters are discussed. Copyright © 2003 Society of Chemical Industry

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Application of AOP pretreatment on a segregated recalcitrant stream may avoid unnecessary consumption of chemicals by biodegradable compounds, thereby imparting cost-effectiveness to the integrated system.

    “Notwithstanding this fact, it should be emphasized that application of AOP pretreatment on segregated recalcitrant stream may avoid unnecessary consumption of chemicals by biodegradable compounds, thereby, imparting cost-effectiveness to the integrated system.124”

  • Treatment schemes based on segregated waste streams coupled with process water recycling have the potential to save money even with high costs per m3.

    “The fact that treatment schemes based on segregated waste streams coupled with process water recycling have the potential to save quite a bit of money even with high costs per m 3 , should be considered while evaluating process viability.124”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
